I can express numbers in standard form and scientific notation. I can compare and order numbers written in scientific notation.

Standard Form  Numbers that do not contain exponents.  million = 12,760,000  millionths =

Scientific Notation  A number that is expressed as a product of a factor and a power of 10.  The factor must be greater than or equal to 1 and less than 10.  a x 10 n, where 1 ≤ a < 10 and n is an integer  3,500,000 = 3.5 x 10 6  = 4 x 10 -5

Compare and Order Numbers in Scientific Notation  First compare the exponents Positive numbers – the greater exponent is greater (bigger) If the exponents are the same – compare the factors

Let’s DO IT!  The diameters of Neptune, Saturn, and Uranus are 4.9 c 10 4 km, 1.2 x 10 5 km, and 5.1 x 10 4 km, respectively. Order the planets from greatest to least diameter. Saturn, Uranus, Neptune
